Professional processing reaming assembly drills, large-diameter assembly cone drills, guide drills, hole cone assembly drills, reaming cone drills. We have professional technical staff, advanced technology and equipment, and use electronic cutting technology to integrate the whole The roller cone bit is cut into a single roller palm, and then processed and assembled according to the predetermined dimensions to become the model required by the customer. This large-caliber assembled drill is mainly used for drilling and reaming during the drilling process, bridge foundation pile engineering, secondary drilling, and plays a guiding role. The types we can process are from 350mm to 1800mm reaming drills. They can be assembled with indented tricone drills or rigid toothed tricone drills. They are mainly targeted at different strata of customers to choose different tooth assemblies. . In addition, we have been supplying 3 to 26 inch solid cone drills and 76mm-445mm diamond PDC composite drill bits for a long time. The brands include Hubei Jianghan, Sichuan Chuanshi, Tianjin Lilin, Jiangxi Feilong, Jiangsu Xinrui and other manufacturers (metal seals, Rubber seal) Tri-cone bit, petroleum bit, mining bit, geological bit and other types of drilling bits.
